This retrospective study was undertaken to estimate i) the surveillance coverage for equine infectious anemia (ETA) based on owner-requested testing, and ii) the incidence of case detection from this surveillance activity to inform a review of Canada's national disease control strategy. Based on sample submissions by accredited veterinarians to laboratories CFIA-approved for EIA testing between 2009 and 2012, the estimated national surveillance coverage was 14% for all years, and 72 cases of EIA were detected. The annual national incidence of EIA detection ranged from 0.03 to 0.08 cases/1000 horses. On average, a greater proportion of the horse population was tested in eastern Canada (32%) than in western Canada (6%, P < 0.0001). The cumulative incidence of ETA detection was higher in western Canada (0.25 cases/1000 horses) than in eastern Canada (0.02 cases/1000 horses, P < 0.0001). This study identified regional differences in owner-requested EIA testing and case detection resulting from this testing activity.
